Case study questions & answers

What is a touch screen?

An electronic visual display

Locates the coordinates of a

user’s touch within display area

Works independently of what is

being displayed on screen

When is it Applicable?

Allows users to interact directly

with what is being displayed

systems, etc. . .

Brief History

1965 : Invented by E.A. Johnson for air traffic control

1971 : Brought into public domain by Elographics, Inc.

1983 : HP-150 (personal touch screen computer) by Hewlett-Packard

1993 : Apple’s Newton and IBM’s Simon

2002 : Microsoft’s Windows XP Tablet

2007 : Apple’s iPhone (Multi-touch)

Multi-touch

Recognize the presence of two or more

points

Not new, Academic and commercial

researchers have been working on multi-

touch technology for years

Used in ATMs, airport kiosks etc.

What is ‘new’ to the touch?

New in mobile market

• Introduced into the market through

Apple’s iPhone (2007)

Replaces traditional keypads

Problems with traditional keypads

Complex UI with lots of menus and buttons

Need to remember the commands

Display must be used for single purpose at a time

Doesn’t support free hand applications

Less flexible

Difficult to adopt for new users

Not user friendly for old users

Not suitable for autistics

Motivation behind Apple’s multi-touch

Control everything using only your fingers

Other companies adopted multi-touch

Microsoft

Dell

Google

HP

Windows Touch

Browse online newspapers

flick through photo albums

shuffle files and folders

—using nothing but your fingers.

Dell Latitude XT tablet PC

Helpful to people who can’t grasp

a mouse

Android’s multi-touch

Native support for multi-touch

HP’s touch smart

Lets you use two fingers at once to manipulate images on the

screen

Make on-screen gestures designating specific commands

without using cursors or scroll bars

Casual computing (For example: Putting on music while

preparing dinner)

Why is Multi-touch everywhere?

More versatile than single-touch interfaces

Allows to use one or more fingers to perform special gestures

Easier to remember than commands

Do not have to be learned

Display used as input device combine with GUI

Real-time interaction for users

Reduces buttons and menus ,making UI simpler

Improved flexibility of customization

Touch technology changes life

Helps an autistic

An easy-to-use computer for students in early grades

Ease of use for older User

Helpful to people who can’t grasp a mouse

Expected Fields

Customers might use touch to place orders with a retailer

Conduct virtual video service calls

Utilize social networking for business

Allows visitors to check out a virtual visitor’s Center

Video chats with remote workers through a built-in Webcam

Use microphone, access e-mail and the Internet, and manage contacts, calendar

items, and photos Without using keyboard and mouse

The revolution touch screen brings

iPhone users in U.S. had grown at a rate of 159 percent in August

2009 compared to past year with 23.8 million users [1]

58 percent of touchscreen mobile devices are expected to contribute

to the worldwide mobile devices sales by 2013 [2]

1. Report of Lipsman (2009)

2. Report of Pettey and Tudor (2010)

The revolution touch screen brings

Market size of touch screen mobile phone

2010 : $4.58 billion

2011 : $6.09 billion

2012 : $9.65 billion

Growth of touch screen mobile phone unit

2010 : 494 million units

2011 : 665 million units

2012 : 1.35 billion units

Limitations

not a realistic replacement for keyboard input

large display requirement

difficult to select small items

are not as accurate as traditional mouse and physical button-navigated applications

having a big bright screen and needing massive computing power to run this means a very low

battery life

in direct sunlight it is much less effective and most of the time very difficult to read the screen

if a touchscreen devise were to crash the whole screen would be unresponsive, and because of

the lack of buttons recovering it would be very difficult

Future of touch technology

It’s too early to know if the new multi-touch interface will ever be as

popular as the mouse-driven graphical user interface

But till today it is showing the positive signs

CASE STUDY QUESTIONS

What problems does multi-touch technology solve?

Helps people with disabilities

Replace the use of mouse and keyboard

Minimize complexity of UI


What are the advantages and disadvantages of a multi-touch

interface?

Advantages

Extremely good for object manipulations

More versatile than single-touch interfaces

Multi touch gestures are easier to remember than commands

Collaborative use


Disadvantages

Eyes on : Touch screen interfaces are nearly all “eyes on”. You cannot type by

touch while your eyes are occupied elsewhere

Hands on : Handheld devices that rely on touch screens for input require two

hands to operate: one to hold the device and the other to operate it.

Fingers on :Your finger is not transparent: the smaller the touch screen, the

more you obscure what is being pointed at


Describe three business applications that would benefit from a

multi-touch interface.

Reading digital material (e-books/ e-mail)

Customers might use touch to place orders with a retailer

Video chats with remote workers through a built-in Webcam


What management, organization, and technology issues must be

addressed if you or your business was considering systems and

computers with multi-touch interfaces?

Management : Cost, technology adoption, training, business objective

Organization : Structure and capability

Technology : Fast server, system ready for use, better

serve, permanent hardware

Any Questions ?
